SIGNALISED INTERSECTION SURVEY METHOD: EMPIRICAL RESULTS OF VALIDATION STUDY
This report is also issued as Australian Road Research Board AIR 347-3. Efficient movement of vehicles in an urban network often means that intersection operation be as efficient as possible (e.g. in terms of total network delay, energy consumption and emissions). There is a growing need to develop a comprehensive, yet simple, survey method to evaluate signalised intersection operation incorporating pertinent performance measures. This report presents an evaluation of a signalised intersection survey method developed at Monash University. In particular, both the theoretical error in the underlying model and the observational error in the survey method are analysed. Both regression analyses and comparisons of delay and vehicle stop distributions show that the survey method performance is quite good. However, it was found that the model seemed to become unstable at intersections with low values of green to cycle time ratio (less than 0.35, say). Further testing is recommended for a range of green to cycle time ratios using a simulation model being developed at Monash University. The observational error in the survey method was found to be negligible, on the basis of regression analyses. Also, it was found that the accuracy of the survey method, in terms of model output, deteriorates minimally when applied over multiple lanes at an intersection. Improvements and modification to the survey method have evolved from the validation study. A change in the survey method to allow it to be applied at coordinated signalised intersections is being considered. The survey method, although simple and easy to use, could find widespread use in the evaluation of numerous transport systems management schemes being investigated by state road authorities.
